VTune Profiler cannot recognize the processor

Hi,

 

VTune installed in a remote Linux system. vtune-self-checker.sh seems to indicate that the SEP driver is loaded and functional (see attached log.txt).

 

Tune GUI running on MacOS and connecting via SSH to the remote Linux machine return the following errors:

x This analysis type is not applicable to the system because VTune Profiler
  cannot recognize the processor. If this is a new Intel processor, please
  check for an updated version of VTune Profiler. If this is an unreleased
  Intel processor, please contact Online Service Center for an NDA product
  package.

x Cannot enable Hardware Event-based Sampling due to a problem with the driver
  (sep*/sepdrv*). Check that the driver is running and the driver group is in
  the current user group list. See the "Sampling Drivers" help topic for
  further details.

 

The processor in the remote machine is Intel(R) Xeon(R) Silver 4210 CPU @ 2.20GHz

 

Any help would be appreciated.

Cheers

Hi,

 

Thank you for posting in Intel communities.

 

To Check the issue from our end could you please share the MacOS processor details?

 

We could see that you have mentioned like the processor in the remote machine is Intel(R) Xeon(R) Silver 4210 CPU @ 2.20GHz (Cascade Lake). But in the log file it is mentioned like skylake.

Could you please verify and confirm the same.

 

Thanks

Hi,

 

I've tried multiple systems with the same result, which is why you saw more than one target processor. Sorry for the confusion. For the purpose of this thread, we can focus on the Skylake use case.

 

The VTune GUI is running in a M1 machine.

Hi,


Could you please share the status of the loaded drivers.


You can check the status of the loaded drivers using the below command:

<oneapi_install_directory>/vtune/latest/sepdk/src/insmod-sep -q


example: /opt/intel/oneapi/vtune/latest/sepdk/src/insmod-sep -q


Thanks

I have also run tune-gui from an Intel based Mac - Intel(R) Xeon(R) W-2150B CPU @ 3.00GHz - and the problem is the same.

Hi,


Could you please try the remote analysis without sep driver (unload it on the target machine)?


Thanks

Hi, I have a similar problem, on a Ubuntu Machine. Could you please guide me with your solution? How do I unload the sep driver?

Vtune Version 2022.4.1 has some major issues on my Ubuntu 20.04. Switching to Vtune 2022.2.0 worked smoothly. Maybe there are some bugs in the newer version of Vtune.

Hi,


We haven't heard back from you. Did you get time to try remote analysis without sep driver ?


Thanks

Yes,

 

I'm running vtune cli in the remote machine then copying the resulting files to the GUI machine.

The issue is that I cannot see the application output in the "Application Output" window in the GUI.
